TQMa95xxSA - YOCTO Linux BSP documentation
Overview
The TQMa95xxSA provides a robust embedded module platform powered by NXP's i.MX 95 processor family. The BSP is based on the Yocto Project using TQ’s meta-tq hardware support layer, with build host setup instructions and BSP sources provided via GitHub.
Please see the meta-tq repository on GitHub for further instructions. A list of supported Yocto images and example configurations is available in the BSP repository GitHub.

BSP Tagging and Revisioning
BSP Git Tagging and Revisioning
TQ manages all Board Support Package (BSP) releases in the meta-tq GitHub repository using annotated Git tags. This ensures each release is traceable to an exact source snapshot and clearly documents which Yocto branch, platform (module) and software revision it covers.
Tag Format:
<YoctoBranch>.<ModuleIdentifier>.TQ.ARM.BSP.<RevisionNumber>
| Component | Description |
|---|---|
| YoctoBranch | Name of the Yocto Project release (e.g. kirkstone, scarthgap) |
| ModuleIdentifier | Target module name when present; omitted entirely for “scarthgap” tags |
| TQ.ARM.BSP | Literal marker for “Board Support Package – Software” |
| RevisionNumber | Four-digit, zero-padded incrementing counter (e.g. 0001, 0002, …) |
Examples:
kirkstone.TQMa64xxL.BSP.SW.0008
scarthgap.BSP.SW.0001 – here no module identifier is used
Supported Platforms Reference:
To see exactly which platforms (machines/boards) each BSP tag covers, open the meta-tq folder in that tag and view its README.md:
/tq-systems/meta-tq/tree/<git-tag>/meta-tq
Click on README.md there to find the full list of Yocto machine names, board variants, RAM options and support status.
Get Notified
In order to be automatically notified of new BSP releases by e-mail, you must activate notifications in the corresponding Github repository.
1. Go to the desired repository in Github (e.g. meta-tq)
2. Click on the notification button
in the top right corner. 3. Log in or create a Github account if you have not already done so.
4. Select “All activity” so that you will be notified of every new release.
Software Versions:
For the exact versions of U-Boot, Linux kernel and other components used in a BSP tag, view doc/README.SoftwareVersions.md in that tag.
tq-systems/meta-tq/blob/<git-tag>/meta-tq/doc/README.SoftwareVersions.md

tqma93xx-mba93xxca/la: fix distroboot flow for rpmsg and lvds configs with linux-imx-tq
Use correct overrides for the BSP flavour to generate the menu entries and use correct overlay name for rpmsg menu item. Otherwise no configurations were generated for NXP BSP flavour and the remoteproc device tree overlay was silently not applied.
